Bringing Kes back could have worked but not in a manner that involved going back in time to destroy Voyager.

If they'd handled it more like the way they handled bringing Daniel back in Stargate the year he was an ascended. They could have even made her a little crazy from isolation. But it definitely should have been more a 'There is a larger threat and I need your help for some reason!' theme.

I didn't watch a whole heck of a lot of Voyager, but this episode is one I saw. I remembered Kes (too cute to forget ), and I remembered her hair changed, then Seven came aboard. Then Kes was gone.

This episode I didn't see the need for at all. If I were a fan of the character, this would not have been a fun watch. It'd be like bringing back Scotty in Relics, only to have him a homicidal, vengeful killer or something. What a slap to fans of the character!

if it weren't for the pinwheel entity in TOS: Day of the Dove, we might interpret Scotty's hysterics on the bridge as an example of what happens when didn't have his morning Scotch. "Keep your Vulcan hands off me!"
